ABSTRACT
STUDY DESIGN: Retrospective population-based database analysis from the Physician/Supplier Procedure Summary Medicare/Medicaid Dataset. OBJECTIVE: To provide a comprehensive analysis of trends in spinal orthosis utilization over a 12-year period. SUMMARY OF BACKGROUND DATA: Widespread prescription of spinal orthosis persists, despite evidence suggesting equivocal efficacy in many spinal conditions. The utilization of spinal orthosis on a national level, including prescribing specialty data, has not been previously analyzed. METHODS: Healthcare common procedure coding system (HCPCS) codes for cervical (CO), thoracic-lumbar-sacral (TLSO), lumbar (LO), lumbar-sacral (LSO), and cervical-thoracic-lumbar-sacral (CTLSO) orthosis were used to determine spinal orthosis utilization from 2010 to 2021. Provider specialty codes were utilized to compare trends between select specialties. Additionally, a neurosurgical CO analysis, based on subclassifications of cervical bracing, was performed. Linear trendlines were implemented to elucidate and present trends by slope (ß). RESULTS: Among 332,241 claims, decreases in CO (ß=-0.3387), TLSO (ß=-0.0942), LO (ß=-0.3485), and LSO (ß=-0.1545) per 100,000 Medicare Part B enrollees and CTLSO (ß=-0.052) per 1,000,000 Medicare Part B enrollees were observed. Decreases among neurosurgery (ß=-7.9208), family medicine (ß=-1.0097), emergency medicine (ß=-2.1958), internal medicine (ß=-1.1151), interventional pain management (ß=-5.0945), and chiropractic medicine (ß=-49.012), and increases among orthopedic surgery (ß=5.5891), pain management (ß=30.416), physical medicine and rehabilitation (ß=4.6524), general practice (ß=79.111), and osteopathic manipulative medicine (ß=45.303) in total spinal orthosis use per 100,000 specialty claims were observed. Analysis on subclassifications of cervical orthosis among neurosurgeons revealed decreases in flexible (ß=-1.7641), semi-rigid (ß=-0.6157), and collar bracing (ß=-2.7603), and an increase in multi-post collar bracing (ß=2.2032) per 100 neurosurgical cervical orthosis claims. CONCLUSIONS: While utilization of spinal orthosis decreased between 2010-2021, increased utilization was observed among a subset of specialties. Identifying these specialties allows for focused research and educational efforts to minimize unnecessary durable medical equipment use for effective healthcare spending.
